VALVE.

Specication of Letters Patent.

Patented Jan. 9,1912.

Application filed' May a2, 1911. serial No. 628,627.

`tion of inlets, outlets and cut offs, so ar.

ranged that I am able, with one turn of the valve stem, to admit water of one temper ature, then, in addition, to admit water of another temperature, the water of both temperatures commingling and being dis! charged at the thus regulated temperature, and finally to entirely cut off Water of the first temperature' and admit only that of .the last temperature.

Figure 1,'-is a central. vertical sectional view of a valve embodying my invention, taken on the line which cuts the inlet and outlet. Fig. 2, is in part, a sectional view on the line showing the discharge outlet, and in part, a side view of the complete device.

Fig. 3, is a horizontal sectional view on line -3-3 of Fig. 2.

This valve consists of a casing 4, divided into an upper chamber 6, and a lower chamber 5, by a diaphragm or central portion 7. A sleeve 8, extends upward into thc upper chamber and downward into the lower chamber, projecting a short distance into each, said sleeve, as shown, being made inte,

y gral with the diaphragm or central portion of the valve itself. w

9 is the cold water inlet leading from the threaded opening, into the lower chamber ofthe valve casing. v

I10 is the hot water inlet, constructed as a passage leading from the threaded opening at the side, directly into the space within the sleeve 8.

11 is the discharge opening and is connected by the passage shown Ain Fig. 2, with the upper chamber 6, of the valve casing. The lower chamber of the valve casing is supplied with a valve disk 12, provided with astem 14, which reaches up into the space within the sleeve aforesaid. It is preferably provided with a rubber washer tom-- sure its tight setting upon the lower end of the sleeve or flange 8. The lower part of the casing is apertured and threaded, as shownat 15, to receive a recessed plug 16, threaded to engage the thread of orifice 15 and provided with a spring 17, seated in its recess and adapted, when the plug is in` place, to

bear upon the lower end of the valve 12, so as to hold that to its seat 18, when the position of the stem permits, though the spring is not absolutely necessary. When this valve is tightly seated upon its seat, water may enter chamber 5, through the cold water inlet, but cannot escape therefrom. The upper end of the casing is also threaded and provided with a plug 19, which screws into said thread and is itself internally threaded, with a quick acting thread 20. In

this quick acting thread 20 there is located ,a second valve 21, provided on its exterior.

with a quick acting thread 22, adapted to take with the quick acting thread 2,0, and' at the end with a valve disk 24, preferably provided with a rubber washer 25, seated in a recess cut inits face. It has also a stem 26, extending out through the en d of plug 19, and 4adapted-to receive a handle or other means for turning the valve. A stuling box plunger 28, is preferably provided to insure against leakage` between the valve stem and the apertured threaded' plug, 19. Below the valve disk 24, the valve is provided with a hollow cylindrical extension 27, adapted to pass down inside of the sleeve 8, It is provided' with a series of apertures 29, which when the device is assembled may `lie in a plane below the bottom edge of sleeve 8, and a single aperture 30, will then register with the aperture l0 from the hot water inlet. The depth of this hollow cylinder and vthe length of the stem of valve 12 are so proportioned that when the disk is closed against 'its seat,-the said stem rests upon the bottom of the recessed or hollow portionI of said disk, but holds disk 12 from its seat. a

The operation of the valve is as follows.' Normally thedisk 24 is pressed tightly against its seat on the upper face of sleeve (or seat) 8, thus closing all passages from the inlets to -the outlet. At the same time, by reason of the proportions of valve stem, 14, the valve disk 12 is held below its seat and water entering the cold water inlet may pass to chamber 5, then between disk-12 and its seat, into the hollow cylinder v27. A very v ting the hot water to a stem extending through the casing,

' therein and passes out in the manner already described. Further turning of the valve handle in the direction of the initial movement, carries the valve disk 21 up until the valve stem 14 resting upon the bottom thereof, israised suiiiciently to permit the disk l2 to seat itself upon t-he lower end of the sleeve (or seat) 8, thus cutting off the cold water, that movement of t-he disk being aided by the spring 17. It is thus seen'that v by the turning of the valve stem, only a few degrees, the objects desired are attained. First turning ony the cold water, then securing the passage of warmer liquid by permitenter and mix with the cold, gradually increasing the quantity of hot water admitted up tothe limit of its temperature, and then shutting oil the cold water.-

What I claim as my invention and desire to secure by Letters Patent is 1. In a valve the combination of a casing provided with a cold water port, a hot water port,'a discharge port, two chambers, a connecting passage leading from one chamber to the other chamber, provided with valve seats at its respective ends, a hollow rotatable plug, located within said passage and provided with a valve disk and an aperture leading through the wall of the plug on a line below the disk and above the valve seat, when the valve is open, quick acting threads on the valve disk and the valve casing in coperative engagement with each other,

a assage leading from the upper chamber? to the main discharge port, a spring, a spring pressed valve adapted to close the lowerend of the connecting passage,y and provided water port, a discharge port, two chambers, l

a connecting passage leading from one chamber to the other chamber, provided 'with valve seats at its respective ends, a

hollow rotatable plug, located within said passage and provided with a valve disk and an aperture leading through the wall of the plug on a line below the disk and above the valve seat, when thevalve is open, quick' acting threads on' the. valve disk and the valve casing, in coperative engagement with each other, a-stem extending through the casing, a passage leading from the upper chamberto the main discharge port, a valve, adapted to close the lower end of the connecting passage, andprovided with a stem reaching to and bearing against said valve disk, an inlet leading from the cold water port into the lower chamber, an inlet leadlIn testimony whereof, I have signed myname to this specification in the presence of two subscribing witnesses, this 3rd day of May 1911.
